git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@63097 91177308-0d34-0410-b5e6-96231b3b80d8
2009-01-27PTH: Use Token::setLiteralData() to directly store a pointer to cached ↵Ted Kremenek
spelling data in the PTH file. This removes a ton of code for looking up spellings using sourcelocations in the PTH file. This simplifies both PTH-generation and reading. Performance impact for -fsyntax-only on Cocoa.h (with Cocoa.h in the PTH file): - PTH generation time improves by 5% - PTH reading improves by 0.3%. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@63072 91177308-0d34-0410-b5e6-96231b3b80d8

2009-01-26This change refactors some of the low-level lexer interfaces a bit.Chris Lattner
Token now has a class of kinds for "literals", which include numeric constants, strings, etc. These tokens can optionally have a pointer to the start of the token in the lexer buffer. This makes it faster to get spelling and do other gymnastics, because we don't have to go through source locations. This change is performance neutral, but will make other changes more feasible down the road. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@63028 91177308-0d34-0410-b5e6-96231b3b80d8

2009-01-20Remove ScopedDecl, collapsing all of its functionality into Decl, soDouglas Gregor
that every declaration lives inside a DeclContext. Moved several things that don't have names but were ScopedDecls (and, therefore, NamedDecls) to inherit from Decl rather than NamedDecl, including ObjCImplementationDecl and LinkageSpecDecl. Now, we don't store empty DeclarationNames for these things, nor do we try to insert them into DeclContext's lookup structure. The serialization tests are temporarily disabled. We'll re-enable them once we've sorted out the remaining ownership/serialiazation issues between DeclContexts and TranslationUnion, DeclGroups, etc. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@62562 91177308-0d34-0410-b5e6-96231b3b80d8

2009-01-17this massive patch introduces a simple new abstraction: it makesChris Lattner
"FileID" a concept that is now enforced by the compiler's type checker instead of yet-another-random-unsigned floating around. This is an important distinction from the "FileID" currently tracked by SourceLocation. *That* FileID may refer to the start of a file or to a chunk within it. The new FileID *only* refers to the file (and its #include stack and eventually #line data), it cannot refer to a chunk. FileID is a completely opaque datatype to all clients, only SourceManager is allowed to poke and prod it. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@62407 91177308-0d34-0410-b5e6-96231b3b80d8

2009-01-17Instead of iterating over FileID's, have PTH generation iterate over theChris Lattner

2009-01-15IdentifierInfo:Ted Kremenek
- IdentifierInfo can now (optionally) have its string data not be co-located with itself. This is for use with PTH. This aspect is a little gross, as getName() and getLength() now make assumptions about a possible alternate representation of IdentifierInfo. Perhaps we should make IdentifierInfo have virtual methods? IdentifierTable: - Added class "IdentifierInfoLookup" that can be used by IdentifierTable to perform "string -> IdentifierInfo" lookups using an auxilliary data structure. This is used by PTH. - Perform tests show that IdentifierTable::get() does not slow down because of the extra check for the IdentiferInfoLookup object (the regular StringMap lookup does enough work to mitigate the impact of an extra null pointer check). - The upshot is that now that some IdentifierInfo objects might be owned by the IdentiferInfoLookup object. This should be reviewed. PTH: - Modified PTHManager::GetIdentifierInfo to *not* insert entries in IdentifierTable's string map, and instead create IdentifierInfo objects on the fly when mapping from persistent IDs to IdentifierInfos. This saves a ton of work with string copies, hashing, and StringMap lookup and resizing. This change was motivated because when processing source files in the PTH cache we don't need to do any string -> IdentifierInfo lookups. - PTHManager now subclasses IdentifierInfoLookup, allowing clients of IdentifierTable to transparently use IdentifierInfo objects managed by the PTH file. PTHManager resolves "string -> IdentifierInfo" queries by doing a binary search over a sorted table of identifier strings in the PTH file (the exact algorithm we use can be changed as needed). These changes lead to the following performance changes when using PTH on Cocoa.h: - fsyntax-only: 10% performance improvement - Eonly: 30% performance improvement git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@62273 91177308-0d34-0410-b5e6-96231b3b80d8
2009-01-15PTH: Embed a persistentID side-table in the PTH file that is sorted in theTed Kremenek
lexical order of the corresponding identifier strings. This will be used for a forthcoming optimization. This slows down PTH generation time by 7%. We can revert this change if the optimization proves to not be valuable. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@62248 91177308-0d34-0410-b5e6-96231b3b80d8
